Abstract: ABSTRACT OF THE DISCLOSURE     A vehicle is provided for use in a toy vehicle game including an endless track defining at least two parallely extending vehicle lanes in which two or more toy vehicles are adapted to be operated.  The toy vehicle in-cludes a reversible rotary drive motor and a transmission operatively engaged between the motor and two drive wheels for rotating one or the other of the drive wheels in response to the direction of rotation of the drive motor, thereby biasing the car against one or the other of the side walls of the track to guide the vehicle along its path of travel in one or the other of the lanes.  The vehicle is used on a track which includes electrical contact strips which supply power to the drive motor of the vehicles through current collectors mounted thereon.  A control system permit the operators to separately and independently control current collectors mounted thereon.  A control system permits the operators to separately and independently control current to the contact strips and also to selectively reverse the polarity of the current so that the operators can vary the speed of their associated vehicles and cause the vehicles to move from one lane to the other.

Abstract: ABSTRACT           An engine comprises at least one cylinder and preferably several cylinders side-by-side.  Each cylinder comprises a toroidal cylinder and has a piston which revolves around the cylinder.      The piston is fixed to the periphery of a disk fixed to the main shaft which coincides with the axis of the cylinder.  At one position of the cylinder a gate is installed which seals the cylinder into two sections.  On one side of the gate is an inlet port and on the opposite side an exhaust port.  A valve controlled by a cam shaft timed from the main shaft controls the inlet port.          A gaseous medium is externally heated in a heater and is introduced under pressure through the inlet port and drives the piston around the cylinder;  the medium in the cylinder ahead of the piston from the previous cycle is discharged through the exhaust port and cooled and then reheated.  The valve is manually (or pedally) con-trolled to cut off to maintain proper speed for the load on the main shaft.  The valve also cuts off intake as the piston approaches the gate.  The gate is opened either by contact with the piston or other means and is closed behind the piston.

Abstract: DYNAMIC PLOW ASSEMBLY AND METHOD OF OPERATING SAME                 (Abstract of the Disclosure) The specification and drawings disclose a plow assembly useful for burying an elongated flexible member, such as a plastic drainage pipe, tube or cable at a pre-determined depth beneath ground level.  The disclosed ap-paratus comprises a frame assembly adapted to be pulled by a tractor type vehicle and having a vertically-extending plow support unit.  At the lower end of the plow support unit, there is mounted a dynamic plow unit which includes an elongated, generally horizontally-extending base.  The forward end of the plow unit includes a plow nose portion having an inclined top surface.  The top of the plow unit is defined by a plate member having an upper surface which extends generally parallel to the base, rearwardly from the nose and is mounted for pivotal movement about a transverse axis closely adjacent the nose portion.  A hydraulic cylinder is provided for oscillating the upper member about the axis.          According to the disclosed method, the upper member is continuously oscillated between a first position where it is generally parallel or at an angle of about 4° or less relative to the base of the plow unit to a second position wherein the top surface forms an angle in the range of 15 to 30 degrees relative to the base.  Additionally, the oscillation is carried out at a range of from 20 to 120 cycles per minute with the upward portion of each oscillation or cycle from the first to the second position of the upper member being slower than the downward or return portion of each oscillation or cycle from the second back to the first position.  Alternatively, the plow nose portion may include a vibrator or a lubricant release for reducing sliding fric-tion of the unit as it is moved through the ground.  For operating at increased depths, a pair of in line spaced apart frame assemblies may be employed wherein the dynamic plow units are disposed at different vertical depths.  The following or rear plow unit is spaced to trench at a greater depth than the forward or lead plow unit.

Abstract: APPARATUS AND METHOD OF ASSISTING  PILE DRIVING BY ELECTRO-OSMOSIS                   Abstract of the Disclosure An apparatus and method for assisting the driving of an electrically conductive pile into soil containing water by electr-o-osmosis in which electrical direct current is directed through the soil for reducing friction between the pile and the soil.  The outside of the pile is coated with a dielectric coating but the lower end of the pile is uncoated for providing an electrical cathode at the lower end.  The negative output of a d-c power source is connected to the conductive pile thereby placing the electrical cathode at a negative potential.  The positive output of the d-c power source is connected to an anode which is posi-tioned in the water causing the water to move from the anode to the cathode through the soil making the pile easier to drive into the soil.  Preferably, the width of the uncoated cathode is approxi-mately equal to the width of the pile.  In the case of assisting the driving of an electrically conductive hollow pile, a dielectric coating is provided on both the inside and outside of the pile but with the lower end of the pile being uncoated for providing an electrical cathode at the lower end.  The negative output of a d-c power source is connected to the conductive pile, a first electrode is positioned outside of the pile and in the water and-connected to the positive output of the d-c power source, and a second anode is positioned inside of the hollow pile in the water and connected to the positive output of the power source.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to novel supported catalysts and a process for their preparation which is characterised in that inert support material, having a surface area of less than 20 m2/g, is impregnated to saturation with a base, then drying the impreg-nated support and impregnating it in a manner which is in itself known with a metal salt solution and/or noble metal salt solution in  an amount such that the support contains 0.01 to 50 gram equiva-lants of base per gram equivalent of metal.  The invention further relates to the use of the novel catalysts for catalytic hydrogenat-ion, dehydrogenation, hydrogenolysis, oxidation, polymerisation, isomerisation or cyclisation reactions.  This process provides catalysts with an enriched catalyst layer directly below the sur-face, thus effecting savings in the impregnated metal, which is especially significant for the expensive noble metals.  These catalysts also exhibit longer life, resistance to poisoning, and produce fewer by products compared to conventional similar high-surface area catalysts.
